Cover safety structure of a pressure cooker lid

Abstract

The invention provides a pressure cooker cover closing safety structure and belongs to the technical field of cookers. The technical problem that an existing pressure cooker cover has the safety risk and the like is solved. A pressure cooker cover comprises a cover body, a clamp and a cover piece, wherein a sealing rubber ring is arranged on the inner side edge of the cover body. The cover closing safety structure comprises an ejection rod and an elastic part, a through hole is formed in the cover body, the ejection rod penetrates into the through hole, an air passing gap is reserved between the inner walls of the ejection rod and the through hole, the ejection rod is located between the sealing rubber ring and the cover piece, the elastic part makes the outer end of the ejection rod always abut against the cover piece, the inner side face of the cover piece is provided with an abutting plane and an oblique yield plane, the inner end of the ejection rod abuts against h the sealing rubber ring and a ventilation gap is formed between the sealing rubber ring and the inner side face of the cover body when the outer end of the ejection rod abuts against the abutting plane. The inner end of the ejection rod is separated from the sealing rubber ring when the outer end of the ejection rod abuts against the oblique yield plane. The pressure cooker cover closing safety structure has the advantages that the pressure in the pressure cooker can be prevented from rising when the pressure cooker cover is not completely closed on a cooker body.

Description

technical field [0001] The invention belongs to the technical field of cooking utensils, and relates to a pressure cooker, in particular to a lid closing safety structure of a pressure cooker lid. Background technique [0002] The pressure cooker ensures the airtightness of the pressure cooker during cooking, and realizes the increase of the pressure inside the pressure cooker, so as to achieve the purpose of heating the cooked food to above 100°C. Meal time saves energy. [0003] With the advancement of technology, there are more and more types of pressure cookers. According to the connection mode of the pot cover and the pot body, one of them is a clamp-type pressure cooker, such as a clamp with driving and self-locking structure disclosed in Chinese patent documents. Clamp type pressure cooker [Authorization Notice CN204192340U], the lid of this type of pressure cooker is provided with a clamp assembly, the clamp assembly includes a clamp, a cover piece and a handle, the...

AI Technical Summary

Problems solved by technology

[0004] In order to avoid excessive pressure in the pressure cooker, the current pressure cooker lid will adopt the structure of a stop rod to realize exhaust, or use a pressure valve to adjust the pressure in the pressure cooker, such as the clamp-type opening and closing lid disclosed in Chinese patent documents Pressure cooker [authorized announcement number CN2310519Y], the above-mentioned exhaust structure is based on the normal lid and body of the pressure cooker to ensure the safety of the pressure cooker, but at present, when people use the clamp type pressure cooker, there is a problem that the handle does not rotate properly. In place, the clamps are not fully moved to the position where the lid and the pot body are clamped. At this time, the connection strength between the lid and the pot body is low. When the pressure in the pressure cooker rises to a certain strength, the pressure Not enough pressure to push the stop lever or open the pressure valve, but the pressure may push the lid off the pot, posing a safety risk
